Key Features

1. Conformal Coating (“C”): Enhanced protection for harsh, humid, or corrosive environments

2. Wide AC Input: 100–276 V AC, global compatibility

3. Compact & Standalone: Mounts directly to Quantum backplane; no external DC needed

4. High Efficiency: Low harmonic distortion (≤10%)

5. Built‑in Protection: Overvoltage, overload, short‑circuit safeguarding

6. Discontinued: Replaced by newer Quantum power supplies

Applications

• Modicon Quantum PLC systems (CPU, backplane, I/O power)

• Harsh environments: chemical, water/wastewater, coastal, mining

• High‑humidity, dusty, or corrosive industrial sites

• Hot standby kits: 140CHS41010 / 41020 (standard power supply)

Differences

• 140CPS11100: Standard (non‑coated), 5.1 VDC 3 A, 120/230 V AC

• 140CPS11100C: Conformal coated version (harsh environment)

• 140CPS21100: Higher power (8 A), wider temp range, non‑coated

• 140CPS21100C: 8 A + conformal coated
